Single-qubit detection by collective phase imprinting
Kritsana Srakaew, Pascal Weckesser, Daniel Adler +4
The amplification of quantum information carried by a single quantum excitation is a recurring challenge across diverse quantum platforms. The coupling between a single qubit and a…
Qutrit entanglement and joint multi-parameter estimation in an optical clock platform
Ohad Lib, Shuheng Liu, Maximilian Ammenwerth +7
Quantum metrology harnesses entanglement to improve measurement precision beyond classical limits. While standard protocols rely on two-level qubits to estimate a single parameter,…
A cryogenic neutral-atom platform with full optical access and 2-hour trap lifetime
Akhil Kumar, Lorenzo Festa, Avishay Grinberg +10
The paper presents a cryogenic neutral‑atom setup that achieves up to two‑hour vacuum‑limited trapping of single 88Sr atoms in an optical tweezer array while maintaining full optic…
Engineering Quantum Many-Body Scars through Lattice Geometry
Erick Parra Verde, Kevin P. Mours, Johannes Zeiher +2
Quantum many-body scars enable persistent non-ergodic dynamics in otherwise thermalizing systems, yet their stabilization typically relies on fine-tuned initial states or engineere…
Kinetically constrained cavity QED: from blockaded ferromagnetism to long-range quantum scars
Hossein Hosseinabadi, Riccardo J. Valencia-Tortora, Aleksandr N. Mikheev +4
Rydberg-cavity systems are emerging as promising platforms for quantum simulation and quantum information processing. These hybrid architectures combine two complementary interacti…
Velocity-Enabled Quantum Computing with Neutral Atoms
Ohad Lib, Hendrik Timme, Maximilian Ammenwerth +5
Realizing error-corrected logical qubits is a central goal for the current development of digital quantum computers. Neutral atoms offer the opportunity to coherently shuttle atoms…
